wireshark does not capture the packets from xilinx FPGA

  • retag add tags

Hi, I have installed wireshark version 3.0.2 with npcap 0.995 in windows 10 Pro 64 bit PC. Wireshark is displaying the packets whenever the PC is connected to LAN. When we try to test the Ethernet interface of xilinx FPGA , packets from FPGA's MAC ID is not displayed.

The same wire shark is working fine with other windows 10 Pro PC.

The same wire shark is working fine with other windows 10 Pro PC.

Is it working on the other machine when it's connected to the Ethernet interface of the FPGA?

You must be aware of the fact that before Wireshark gets its hands on an Ethernet frame a lot of other stuff needs to go right first. It is the networking hardware that handles the layer 1 and layer 2 stuff, i.e. on the cable the frame must have a proper preamble, start delimiter and then the destination MAC, etc. If the PSN in the FPGA isn't encoding this stuff right the network interface in the PC won't accept the frame and pass it up the network stack.

Have a look at the PC's network interface performance counters, to see if any of the error counters count up when the FPGA is supposed to send frames.
